There have been no offers for sale anywhere in the world prior to the effective filing date of this Application and no accessibility to one of ordinary skill in the art.

The Inventor/Applicant asserts that no publications nor advertisements relating to sales, offers for sale or public distribution occurred more than one year prior to the effective filing date of this application. Any information about the claimed plant would have been obtained from a direct or indirect disclosure from the Inventor/Applicant. Inventor/Applicant claims a prior art exception under 35 U.S.C. 102(b)(1) for disclosure and/or sales prior to the filing date but less than one year prior to the effective filing date.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum X morifolium and hereinafter referred to by the name ‘G21VIG05DY’.

The new Chrysanthemum plant is a product of a planned breeding program conducted by the Inventor in Oostnieuwkerke, Belgium. The objective of the breeding program is to create new uniformly mounding and freely flowering Chrysanthemum plants with unique and attractive inflorescence form and ray floret coloration.

The new Chrysanthemum plant is a naturally-occurring whole plant mutation of Chrysanthemum X morifolium ‘Vigorelli Violet’, disclosed in U.S. Plant Pat. No. 23,965. The new Chrysanthemum plant was discovered and selected by the Inventor as a single flowering plant from within a population of plants of ‘Vigorelli Violet’ in a controlled greenhouse environment in Oostnieuwkerke, Belgium in October, 2017.

Asexual reproduction of the new Chrysanthemum plant by vegetative terminal cuttings was first conducted in a controlled greenhouse environment in Oostnieuwkerke, Belgium in January, 2018. Asexual reproduction by vegetative terminal cuttings has shown that the unique features of this new Chrysanthemum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘G21VIG05DY’. These characteristics in combination distinguish ‘G21VIG05DY’ as a new and distinct Chrysanthemum plant:

-   -   1. Upright, outwardly spreading and uniformly rounded plant         habit; vigorous growth habit.     -   2. Freely branching habit; dense and full plant habit; flexible         stems.     -   3. Dark green-colored leaves.     -   4. Uniform and freely flowering habit.     -   5. Long flowering period.     -   6. Medium-sized decorative type inflorescences with ray florets         that are golden yellow in color.     -   7. Excellent garden performance.

Plants of the new Chrysanthemum can be compared to plants of the mutation parent, ‘Vigorelli Violet’. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘Vigorelli Violet’ in ray floret color as ray florets of plants of the new Chrysanthemum are golden yellow in color whereas ray florets of plants of ‘Vigorelli Violet’ are dark red purple in color becoming lighter red purple with development giving a bi-colored appearance.

Plants of the new Chrysanthemum can also be compared to plants of Chrysanthemum X morifolium ‘PPP COL OR07’, disclosed in U.S. Plant Pat. No. 20,355. In side-by-side comparisons, plants of the new Chrysanthemum differ primarily from plants of ‘PPP COL OR07’ in the following characteristics:

-   -   1. Plants of the new Chrysanthemum are smaller and not as         vigorous as plants of ‘PPP COL OR07’.     -   2. Leaves of plants of the new Chrysanthemum are brighter green         in color than leaves of plants of ‘PPP COL OR07’.     -   3. Plants of the new Chrysanthemum flower later than plants of         ‘PPP COL OR07’.     -   4. Ray florets of plants of the new Chrysanthemum are golden         yellow in color whereas ray florets of plants of ‘PPP COL OR07’         are bronze in color with darker red centers.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates the overall appearance of the new Chrysanthemum plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The photograph comprises a top perspective view of a typical flowering plant of ‘G21VIG05DY’ grown in a container.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations and measurements describe plants grown in 19-cm containers in an outdoor nursery in Oostnieuwkerke, Belgium under natural daylengths during the autumn and employing cultural practices typically used in commercial Chrysanthemum production. During the production of the plants, day temperatures ranged from 20° C. to 25° C. and night temperatures ranged from 12° C. to 18° C. Plants were 20 weeks old when the photograph and detailed description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
